Well the range largely depends on the power you are delivering to the antenna. The gain of the antenna + power = the radiated power so what you feed the antenna with makes a very large difference in range. As does the location of the antenna - indoors or outdoors. (Indoor antennas are highly limited in range by the building they are within.)
If you feed it with a normal household router you are feeding 30-50mw of power. Your range is probably about 1/4 mile.
If you feed it with a more commercial grade wifi router that could be improved to say 400mw which is several times more and that much more coverage area.
Also how much cable is between the antenna and the router?
The max allowed ERP has to be below the Fed Rules. If you are at the MAX for the rules then you can send the signal for miles. (It is line of site but that covers a lot of territory)
One of the easiest to use routers for public wifi use is the
AirEpoch Wireless gateway. It has user management/radius built in and can isolate wireless from wired users etc. Its output is 400mw at the high setting and allows other settings.
Hope that helps
